Hi there
Yes - I take my stuff to Tranny's (as in "transparencies" - not cross-dressing) in Crows Nest. Phone: 9902 2400
They have a website:
http://www.trannys.com.au/
These guys are film transparency developing and scanning specialists. Very, very good. They will also take into account that you are an astrophotographer and apply the necessary safeguards to the process for you.
Cheers
Chris
